My daughter is nine months and has always been a bad sleeper. I am up and down with her all night. She will sleep for ages in my arms but hates going in the cot. She keeps wanting to breastfeed all through the night. HV's advice is to try to settle her in the cot but she works herself up so much that I can't keep going with it and end up picking her up. I feel so sleep-deprived and am thinking of starting co sleeping just so that we can all try to get some rest. Please can you advise me? Should I start co sleeping at nine months if we've got this far without it? I just don't know what else to do.
